Tips for senior golfers

I am 77 years of age and I get inundated with emails from golf experts about how to add 30 yards to a drive and all other tips etc etc which frankly are useless to senior golfers who no longer have the flexibility in their body and club head speed that they once had when young. I don’t know what the statistics are to the amount of senior golfer who play several times a week to weekend golfer but it must be close. But I have yet to see anybody giving tips on how senior golfer can improve their game. For example last year I selected a 2nd hand driver in a pro shop to use on a driving range and rather liked it, particularly the whip in the shaft, and later discovered it was a ladies club. So I bought it and had a thicker grip fitted. So does anybody know of any You Tube sites to help senior golfers to improve their game?

Please don't take this the wrong way, but a tech savvy senior...I'm impressed! Which leads me onto my point, unfortunately i'm not sure there is a specific coach on YouTube who gives 'online lessons' tailored towards senior golfers, as the market isn't really there just yet. Maybe submit a question to Mark Crossfield, he's kind of a celebrity in the YouTube golf world and would probably love a question on how to help improve a senior golfer as I'm guessing it isn't something that is sent to him often. Let us know on here if there's anything specific you want to improve, maybe someone will be able to help? Again, I hope the content / tone of my post isn't off putting etc. Just trying to be informative.
